Key points

• ·De minimis is suspended indefinitely: non-postal modes since 2026-06-24, international mail since 2026-07-24. The US$800 duty-free entry no longer exists.
• ·No federal VAT or GST. State sales or use tax is a separate matter handled after import, not at the border.
• ·US$2,500 separates informal from formal entry. Mail shipments up to US$2,500 in HTSUS chapters 1-97 may use the new postal informal entry process, with duty due by the 7th day of the month following arrival.
• ·The importer of record may self-file in ACE, but formal entries require a customs bond, and ocean cargo also requires an Importer Security Filing (ISF 10+2) at least 24 hours before loading.
• ·The Section 122 surcharge ended on 2026-07-24, and a Section 301 forced-labour action covering 60 economies took effect the same day. Additional duties appear as HTSUS Chapter 99 lines, so check what is in force on your entry date.

Key points on the origin side

• ·Customs registration as consignor is required before exporting; foreign trade operator registration was abolished from 2022-12-30.
• ·Most goods carry no export duty; only the limited list in the Import and Export Tariff carries an export duty or provisional export rate.
• ·Exports are zero-rated or exempt for VAT, and a qualifying exporter claims the refund at the rate published for the commodity code.
• ·Check the regulatory condition code on the commodity code to see whether an export licence, a dual-use licence (State Council Decree 792) or statutory inspection applies. MOFCOM and GACC publish the dual-use licensing catalogue each year.
• ·Certificates of origin are issued by customs or CCPIT and are what the buyer uses to claim preference at destination.
• ·Statutory inspection is governed by the Catalogue of Import and Export Commodities Subject to Compulsory Inspection (the 法检 catalogue), shown as customs supervision condition A (import inspection) / B (export inspection) on the commodity code and adjusted by GACC announcement from time to time (latest adjustment: GACC Announcement 2026 No. 97, effective 2026-07-16). Check the supervision conditions of your code before declaring.

• · The United States has no federal value-added or goods-and-services tax. Customs collects duty and fees only.
• · Merchandise processing fee: 0.3464% of the entered value on formal entries, with a minimum and maximum re-indexed to inflation each fiscal year. For FY2026 (through 2026-09-30) the range is US$33.58 to US$651.50; for FY2027 (from 2026-10-01) it is US$34.58 to US$670.86. Informal entries pay a flat amount instead — US$2.77, 8.30 or 12.45 in FY2027.
• · Harbor maintenance fee: 0.125% of the value on cargo arriving by vessel.
• · State sales or use tax may apply to the onward sale or use of the goods and is administered by state revenue departments, not by CBP.
